Costa, formerly of the same address, pleaded guilty to one count of the same charge and was jailed for three years, Kent Police said.

After the sentencing, Detective Constable Mark Donovan said: "Despite attempting to distance themselves from the drugs found in their home, it was clear that Daniel Fleming and Alyx Costa were near the very top of the amphetamine supply line.

"Drugs cause significant harm to communities so I am pleased such a large quantity has now been removed from the streets along with two people who belong behind bars."
